14 Claims.

This invention relates to knots used for tying two strands of filamentary material together and more particularly this invention relates to the method used for tying two strands of plastic filamentary material together.

The use of plastic filaments such as polyethylene monofil, nylon or the like in the fabrication of commercial products,.particularly woven material, demands the existence of a method of securely fastening together loose ends of the monofil. Polyethylene monofil possesses an unusual property in that, to the knowledge of the inventor,

two pieces of polyethylene monofi-l could not heretofore be securely fastened by the use of ordinary type knots.

The object of the present invention is to provide a method of tying a simple knot, which when used to tie two pieces or sections of plastic filaments or strands together will hold fast without slipping.

Other objects and advantages of the present invention will become apparent from a study of the illustrations and description hereinafter.

In the drawings Figure l is an illustration of the common square knot which is used as a basis for the present invention.

Figure 2 is an illustration of a granny knot which is also used as a basis in the present invention.

Figure 3 is an illustration of a preferred embodiment of the present invention.

Figures 4 to 11 are modifications of the form of invention shown in Figure 3 which use the square knot as a basis.

Figures 12 to 21 are modifications of the form of invention shown in Figure 3 using the granny knot as a basis.

The basic knots from which the present invention is derived are the square knot and the granny knot as shown in Figures 1 and 2 respectively. Hereafter, for the purpose of clarity, reference character X in Figures 1 and 2 designates the space between the two superimposed overhand Figure 1, and with the square knot lying in the position shown in Figure 1, pass the end I under .The preferred embodiment of the knot the standing portion 3 of the same strand and up over the top and outside part 5 of the square knot down through the loop of the square knot at point 1. Similarly pass the end 2 over the standing portion 4 of the same strand, and down around the outside of part 6 of the square knot and up through the loop of the square knot at 8. The ends I and 2 in all the knots tied should be of suiiicient length to prevent their slipping from the loop of the square knot as the knot is drawn tight. By pulling the standing portions 3 and 4 in opposite directions the knot is drawn tight.

The following modifications of the present invention, as shown in Figures 4 to 11 are all generated from the square knot lying in the position shown in Figure 1.
